-------------------------------
Integrated in HBase-0.92 #63 (See
[https://builds.apache.org/job/HBase-0.92/63/])
HBASE-3417 CacheOnWrite is using the temporary output path for block
names, need to use a more consistent block naming scheme (jgray)

> Currently the block names used in the block cache are built using the
> filesystem path. However, for cache on write, the path is a temporary output
> file.
> The original COW patch actually made some modifications to block naming stuff
> to make it more consistent but did not do enough. Should add a separate
> method somewhere for generating block names using some more easily mocked
> scheme (rather than just raw path as we generate a random unique file name
> twice, once for tmp and then again when moved into place).
